[KeyCAPTCHA]

It seems to be the same spammer group as before installing KeyCAPTCHA. I simply can't believe that all this spam is manual.

Hello, Gladius2007,
"4 signups in a few hours" is not an indication of automated registrations. Hundreds and thousands would have been.
There are no bots without human operators (or human spammers). Those (without human participation or involvement) are called by viruses (but not bots).

KeyCAPTCHA uses geo-cluster of server in 24*7*365 DDOS-resilient centers in different countries and using multiple IP-ddresses. In rare cases of one of such dtacenter is down, our service is redirected to another server in another country. In this case there can be a few dozens seconds delay in KeyCAPTCHA service. Anyway, I cannot understand why you are getting registrations at all (even manual ones) when KeyCAPTCHA service is down. There is something wrong with configuration of your website or it could have been compromised even before KeyCAPTCHA install.

If you believe that there are issues with keycaptcha anti-spam protection (or configuration) on your site, please open support ticket from under logged into keycaptcha.com user.
We can neither identify nor resolve issues by reading forum posts (even less from ones without even indication of any concrete details)

Update:
We checked.
There were some problems on keycaptcha.com webiste due to a maintenance in a datacenter during 1 hour but antispam keycaptcha service worked stable without downtimes due to geo-cluster used.

Open a ticket indicating your (IP-address or website) and the period of time when the issue occured and we shall send you our screenshots of how our captchas were passed and other data to analyze your incident (being spammed).
